You must not have warnings turned on.

@array[ @indices ] is a valid way to produce a slice of array values,  
but when there's only one index, the @ sigil doesn't make much sense.   
And when you have warnings turned on, perl tells you that it doesn't  
make sense:

Scalar value @array[2] better written as $array[2] at <filename> line  
<blah blah>.
